Station performance charts (Potsdam Workshop Spoiler)

[Toshimichi Otsubo]

Hello from Tokyo.

Just 2 weeks before the Potsdam workshop, we have generated a huge number of station-by-station charts so as to assess+assist the productivity and the quality of every SLR station. 

The details are introduced in the 'systematics' session and the 'clinic' session, but you will be able to directly get to the points if you look at them in advance.

This year, in addition to the usual tests, we look into the calibration (= system delay measurement) - frequency, stability, etc.

// Data span: 1 year = July 2015 to June 2016
// POD: software c5++ R874

Hit-rate (observation success rate) over all fly-over observation chances (El > 20 deg)

and 4 resp)

System delay measurement frequency
= Interval between calibration record with different time tags
(blue parts: not a unique measurement? Identical records with different time tags found.)
